EDWARD STONE, OF LOS ANGELES, CALIFORNIA.

RULE-GAGE.

To all whom it may concem:

Be it known that I, EDWARD STONE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Rule- Gage for GagingRound-Edged Lumber and for other Uses, of which the following is aspecification.

The object of this invention is to provide in combination with a foldingrule a cheap and simple device that may be carried on and used with thefolding rule for the purpose of gaging boards having rounded orirregular edges and that may be also very convenient for gaging themargins of door and window casings and also for gaging blind stops ofwindows.

The invention may be put to various uses which may be understood fro-mthe subjoined detailed description.

The accompanying drawings illustrate the invention.

Figure 1 is a view of the invention arranged to be conveniently storedand carried.

Fig. 2 is a view of the invention ad-' justed for use. A fragment of thefolding rule is shown. A pencil at the end of therule indicates the useof the gage for scribing a round-edged board. Fig. 3 is a view showingthe gage slide viewed from the side opposite that shown in Fig. 2. Afragment of the rule is shown and also a fragment of a rabbeted boardhaving a broken tongue to which the gage slide is applied. Fig. .L is aperspective view of the gage slide detached. Fig. 5 is a longitudinalmid-section of the gage slide detached.

a designates a limb of an ordinary folding rule. The gage slide Z)consists of a rec tangular sleeve which may be a section of arectangular tube the bore 0 of which corresponds in cross-sectionapproximately to the cross-section of the limb a of the rule to which itis to be applied. Said gage slide is provided with broad side walls (Z,c, and

narrow edge walls f, g. The side walls d, e, are provided withoppositely arranged transverse orifices h, 2', corresponding in form tothe cross-section of the bore 0 so that the limb a. of the rule whichapproximately fits the bore 0 will also approximately fit the orificesh, 2'. The appliance is therefore adapted to be withdrawn from thelongitudinal position, shown in Fig. 1 on the Specification of LettersPatent.

end of the gage slide than they are to the other and in practice arepreferably arranged only a short distance from the nearest end of thegage slide to form corresponding bars j opposite each other. The widthof said bars preferably corresponds to the thickness of the gage slideZ), and in practice each of said bars will be preferably onefourth of aninch wide so that when the gage slide is applied to a limb of the ruleas shown in Figs. 2 and 3, the limb a of the rule being inserted throughthe perforations h, i, the limb of the gage slide on one side of thelimb a of the rule will project onefourth of an inch. These dimensionsare desirable for the reason that many of the parts to be gag'ed are inthe form of projections of onefourth of an inch, as the margins of doorcasings. The narrow edge walls f, g, are preferably unbroken from end toend of the gage; and one of the side walls, as e, is provided with slitsk, m, that extend a considerable distance alongside the edge walls f, 9,toward the orifices h, 2', thus to provide between the edge Walls a leafspring 01. which may be bent to form a spring having an internal concaveprojection 22 to press upon the face of the rule.

The tube from which the gage is formed may be of spring brass or othersuitable material and the spring tongue at will engage the same withsuitable pressure to avoid accidental removal of the gage slide from itsstored position as shown in Fig. 1.

In practice the gage slide, when not in use, will ordinarily be carriedon a limb of a rule as shown in Fig. l, and when it is desired to usethe gage the slide will he slipped from the rule and reapplied as shownin Figs. 2 and 3.

The use of the gage when the slide is applied as shown in Figs. 2 and 3will be apparent to any skilled person. hen the gage is no longerrequired for use the gage slide may be removed from the position shownin Figs. 2 and 3 and returned to the position shown in Fig. 1. Thegage-slide is preferably five-eighths of an inch wide so that it may beused edgewise alongside the blind stops of windows to gage the extent towhich such stops may project. To thus use said slide it may be appliedlongitudinally of the rule limb and the unfolded rule may be used as ahandle as the gage is run on the casing alongside the blind stop andflatwise against the same.

The gage constructed as shown in the drawings may be used for gaging anywidth less than the full length of the folding rule to which the gageslide is fitted; all that necessary to fit it for this work being toreverse the rule from the position shown in Fig. using the pencil on thelonger instead of the shorter end of the rule. It is under stood thatthe slide may be applied to a rule of any length devoid of joints andthat the purpose of applying it to the folding rule is convenience ofstorage and use.

By making the orifices nearer one end than the other end of the sectionso as to provide a long and a short limb on opposite sides of the rule,the applicability of the rule for use in various situations isincreased. The short limb may be used as indicated in Fig. 3, where itis desired to scribe a tongue and groove board having a broken tonguealong which the gage cannot be run smoothly. and the longer limb servesto allow the gage to be accurately used on round edged lumber asindicated in Fig. 2. and yet the slide or sleeve is small and light andadds practically nothing to the bu k of i the folding rule.

I claim 1. A gage slide for a rule, comprising a tube of oblongrectangular cross-section provided in its wider walls with transverseorifices approximately corresponding in form and size to the bore of thetube, one of the walls of the tube being slit and bent to form a springtongue.

2. A gage comprising a rule and a section of tubing the bore of whichapproximately fits the rule, said tubing being provided with oppositelyarranged transverse orifices adapted to practically fit the rule andthrough which a limb of the rule may be inserted.

3. A gage comprising a rule, and a section of tubing the bore of whichapproximately fits the rule, said tubing being provided with oppositelyarranged transverse orifices through which a limb of the rule may beinserted, said orifices being nearer one end of the tubular section thanthe other.

4:. The combination with the limb of a rule, of a section of tubing thebore of which approximately fits the rule said tubing being providedwith oppositely arranged transverse orifices through which a limb of therule may be inserted, said orifices being nearer one end of the tubularsection than the other, one of the longer side walls of said sectionbeing slitted and said side walls bent at the slitted portion to form aspring to engage the rule.

5. The combination with a folding rule of a tubular section of springsheet metal pro vided with opposite orifices through which the rule maybe inserted and also provided with a spring tongue; said section beingadapted to slide upon a limb of the rule the bore of said section beingadapted to receive a limb of the rule so that said section may beapplied to the rule longitudinally and transversely substantially as andfor the purpose set forth.

6. The combination with a rule, of a slide provided wit-h a bore andwith orifices; said orifices being arranged transversely relative to thebore, so that the slide may be applied transversely to the rule for thepurpose of gaging, and may be applied longitudinally on the rule for thepurpose of storing.

In testimony whereof, I have hereunto set my hand at Los Angeles.California, this 12th day of November, 1909.
